Powerbomb Header:

FOR CLOSED COURSE COMPETITION USE ONLY. NOT INTENDED FOR STREET USE.

The redesigned PowerBomb is a four-stroke header that incorporates FMF’s patented PowerBomb module at a precise location in the initial stage of the header. By positioning this “Bomb” at a key point in the system, increased performance and flow is achieved through the expansion and contraction of exhaust sonics through the system. Result is a flow increase of nearly 10%! The outer chamber in the Powerbomb allows the air to expand, cool and ramp back up at a higher velocity.

Additionally, the PowerBomb is a “pre-muffler” of sorts which helps to lower the bikes sound output by providing more sound absorbing surface area for the sound medium (exhaust gases). On some models, you can choose between a moto or supercross version. The supercross version is designed for more low to mid-range power where the moto version is focused in the mid to upper RPM range.

Q4 Hex S/A Muffler:

The FMF Q has always been in a league of its’ own and our latest Q4 is the most significant upgrade to date.  You don’t need to settle for a plugged up moto muffler hampered by an insert when you can have a compliant muffler engineered for performance.
